In Guerrero, Mexico’s biggest gold producer is about to get even bigger

Thu April 03 2025

With the completion of an unprecedented 7-kilometer-long tunnel, Torex Gold Resources — Mexico’s largest gold producer — anticipates greater operational efficiency at its 29,000-hectare Morelos property in the state of Guerrero.

The underground tunnel, which passes beneath the Balsas River, links the Canadian gold producer’s highly productive El Limón Guajes mine with its new Media Luna project.

The tunnel, completed March 26, is just one part of a massive processing plant tie-in project designed to link the two mines and enhance Torex Gold’s environmental sustainability in Mexico, company officials said.

Torex Gold CEO Jody Kuzenko did the honors of detonating the final explosives to complete the tunnel after which he praised the engineers and workers who completed the tunnel in record time. The tunnel — 6 meters wide and 6.5 meters high — was completed three months ahead of schedule.

In July 2024, El Limon-Guajes surpassed Peñasquito to become Mexico’s largest gold producer, with an output of 453,800 ounces. The Peñasquito mine — operated by Canada’s Newton Corporation — is located in the state of Zacatecas.

According to a project overview published by Torex Gold, Media Luna — discovered in March 2012 — is an underground deposit that primarily contains gold, copper and silver mineralization.

In addition to the tunnel, the Media Luna expansion includes a water treatment plant and a new “flotation circuit” — a metallurgical process that uses air bubbles and chemicals to separate valuable minerals from waste rock.

From August 2022 through September 2024, Torex Gold spent US $840 million on the construction and engineering project at Media Luna.
